Software RAID will look after the RAID management through software. The dedicated processing power for the disk management array is drawn from the server resources in this RAID. 

Software-based RAID will leverage some of the system’s computing power to manage the RAID configuration. If you’re looking to maximize the performance of a system, such with a RAID 5 or 6 configuration, it’s best to use a hardware-based RAID card when you’re using standard HDDs.
